We define the cpu efficiency of a computer system as the percentage of cpu time used for useful work. The scheduling method used is round robin with a time quantum of Q, if on the average, every process will use 2*Q cpu time before it will block on I/O operation for 4*Q time (I/O completion time) and we assume the context switch cost is Q and there are infinite amount of processes in the system, then the cpu efficiency of this system is:

Answers

Answer 1

We define the CPU efficiency of a computer system as the percentage of CPU time used for useful work, the CPU efficiency of this system is approximately 28.57%.

We must ascertain the portion of CPU time that is utilised for productive activity in order to compute the system's CPU efficiency.

We may determine the CPU efficiency in the following manner in the given scenario with round-robin scheduling, particular time quantum, and I/O operation durations:

Let's first think about how long a procedure takes in each stage:

CPU Burst: Before blocking for I/O, each process spends 2*Q CPU time.I/O Wait: The process blocks after the CPU burst until the I/O is finished, which takes 4*Q time.Context Change: The cost of a context change is Q.

The total time for each process is: 2Q (CPU burst) + 4Q (I/O wait) + Q (context switch) = 7*Q.

The CPU efficiency can be calculated as the ratio of CPU Time to Total Time, multiplied by 100 to get the percentage:

Efficiency = (CPU Time / Total Time) * 100

= (2Q / 7Q) * 100

= 2/7 * 100

= 28.57%

Thus, the CPU efficiency of this system is approximately 28.57%.

What source ip address does a router use by default when the traceroute command is issued?

Answers

When sending an echo request message, a router will use the IP address of the exit interface as the source IP address.

What is traceroute IP address?Traceroute is a network tool that determines the "path" packets take between IP addresses. It is also referred to as tracepath or tracert. The hostname, IP address, and ping response time are displayed. Enter the IP address you want to look up. Traceroute ensures that each hop on the path to the destination device drops a packet and sends an ICMP error message. This means that traceroute can calculate the RTT for each hop by measuring the time between sending the data and receiving the ICMP message. The source IP address of an echo request message is the IP address of the exit interface.

Answers

Assume that your body mass index (BMI) program calculated a BMI of 20.6.  The value of category will be option A) overweight.

What is the body mass index  about?

Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women. It is calculated by dividing a person's weight in kilograms by their height in meters squared.

A BMI of 20.6 falls within the normal weight range, which is a BMI of 18.5 to 24.9. However, based on the given code snippet, if the BMI is 39.9 or greater, the category is "morbidly obese." If the BMI is less than or equal to 24.9, the category is "normal." If the BMI is less than 39.9 but greater than 24.9, the category is "overweight."

Therefore, if the BMI calculated by the program is 20.6, the value of the category will be "overweight."

sql server supports ________________ of the ansi-standard data types. a).all. b).none. c).some, but not all

Answers

SQL Server supports some, but not all, of the ANSI-standard data types, providing its own set of data types that align with the ANSI SQL standard.

SQL Server, a relational database management system developed by Microsoft, follows the ANSI SQL standard to a certain extent. While it provides a wide range of data types to accommodate different data requirements, not all of these types align with the ANSI-standard data types. SQL Server introduces its own set of data types that are specific to its implementation, extending beyond what the ANSI SQL standard defines. These proprietary data types offer additional functionality and features tailored to the specific capabilities and optimizations of SQL Server.

However, SQL Server does support many of the commonly used ANSI SQL data types. These include INTEGER, CHAR, VARCHAR, DATE, TIME, TIMESTAMP, and others. These supported ANSI data types are crucial for ensuring compatibility and portability of SQL code across different database systems that adhere to the ANSI standard. Developers working with SQL Server need to be aware of the differences between ANSI-standard data types and the ones specific to SQL Server, ensuring their code remains compatible and interoperable across different database platforms.

Nelson’s Hardware Store stocks a 19.2-volt cordless drill that is a popular seller. The annual demand is 5,000 units, the ordering cost is $15, and the inventory holding cost is $4/unit/year
What is the economic order quantity?
What is the total annual cost for this inventory item?

Answers

The total annual cost for Nelson's Hardware Store's cordless drill inventory item is approximately $774.60.

To determine the economic order quantity (EOQ) and total annual cost for Nelson's Hardware Store's cordless drill inventory item, we need to consider the annual demand, ordering cost, and inventory holding cost. The EOQ represents the optimal order quantity that minimizes the total cost of inventory management. The total annual cost includes both ordering costs and inventory holding costs.

The economic order quantity (EOQ) can be calculated using the formula:

EOQ = sqrt((2 * Annual Demand * Ordering Cost) / Holding Cost per Unit)

Given:

Annual demand = 5,000 units

Ordering cost = $15

Inventory holding cost = $4/unit/year

Using the given values, we can calculate the EOQ:

EOQ = sqrt((2 * 5,000 * 15) / 4) = sqrt(37,500) ≈ 193.65

Therefore, the economic order quantity for the cordless drill is approximately 194 units.

To calculate the total annual cost, we need to consider both the ordering cost and the inventory holding cost. The total annual cost can be calculated using the formula:

Total Annual Cost = (Ordering Cost * Annual Demand / EOQ) + (Holding Cost per Unit * EOQ / 2)

Substituting the given values into the formula:

Total Annual Cost = (15 * 5,000 / 194) + (4 * 194 / 2) ≈ 386.60 + 388 ≈ $774.60

Therefore, the total annual cost for Nelson's Hardware Store's cordless drill inventory item is approximately $774.60.

Answer:

=A$6+B4 will be in B8

=B$6+C6 will be in C10

=C$6+D2 will be in D6

=D$6+E1 will be in E5

Explanation:

$ sign is used to lock a certain column or row value, with the $ sign we can create an absolute reference which will remain unchanged as we copy our formula from one cell to another.

As formulars are copied, the references change respectively.

With =B$6+C1 in C5 ; As we move up or down of cell C5, only the row numbers will change that is formula in C6 becomes =B$6+C2.

As we move left and right, the column alphabet will also experience change like the rows did.

Only the absolute reference won't change no matter the direction.

Hence,

=A$6+B4 ; A and B means one move to the left of C5 and 4 signifies, 3 moves downward of C5 that gives B8

=B$6+C6 ; B and C means no horizontal change, 6 means 5 moves downward of C5 which gives C10

=C$6+D2 ; C and D means 1 move to the right and 2 means one move downward of C5 which gives D6

=D$6+E1 ; D and E means 2 moves to the right and 1 means no vertical change from C5 ; which gives E5
